4 Claims.

My invention relates to the throwing of lines across bodies of water, toa ship in distress, and for other purposes, and has among its objectsand advantages the provision of an improved line thrower.

In the accompanying drawings:

Figure 1 is a, side view of a gun showing my invention applied thereto.

Figure 2 is a plan view of a gun barrel clamp.

Figure 3 is an end view of the clamp.

Figure 4 is an axial view of a line ring to be picked up by theprojectile fired from the gun.

Figure 5 is an enlarged sectional view along the line 5-5 of Figure 2.

Figure 6 is a side and partial sectional view of a line carryingprojectile and its shell.

Figure 7 is a partial sectional View of the projectile.

Figure 8 is a View illustrating the manner in which the line is pickedup by the projectile, and

Figure 9 is a rear end view of the projectile.

In the embodiment of the invention selected for illustration, I make useof a clamp ill comprising band sections i2 curved to fit on the muzzleend of the gun barrel [4. Each section has two flanges It through whichbolts l8 are extended to frictionally secure the clamp to the barrel l4.

Arms 20 are respectively welded to the sections l and arrangedlongitudinally of the barrel Hi, which arms are spaced apart somedistance greater than the bore of the barrel is. These arms extendbeyond the muzzle end of the barrel id and constitute a mount for acarrier or ring 22 attached to a line 24 to be shot to a given location.This line is Wound on a supply spool 26 in the usual manner.

Pins 28 are attached to the arms 20 to prevent the ring 22 from slidingback on the barrel i4, and the ring is prevented from dropping off theforward ends of the arms by springs 3t paralleling the respective arms.The rear ends of the springs lie in grooves 32 extending to the forwardends of the arms, and the springs are attached to the arms by screws 3d.The springs yield and are pressed into the grooves 32 by the ring 22when the latter is pulled oh the arms.

In Figures 6, 7 and 8, two hooks 36 are pivotally connected with a pin38 attached to a bracket 46 at the rear end of a projectile E2 of ashell 44. The bracket do is attached to a pin 44 secured to a bearingbody 36 lying in a recess 48 in the projectile 42. This pin is coaxialwith the projectile. Ball bearings &5 are confined between the body 46and a second body 52 pressed into the recess 48. A retaining plate 54 isattached to the rear end face 56 of the projectile 42 by screw 58.

The hooks 36 lie in the explosive material 80 in the shell 44 and arebiased apart by a coiled spring 62 mounted on the pin 38 and having ends64 bent to engage over the hooks.

When the projectile 42 is fired from the barrel l4, the hooks 38 spreadto connect with the ring 22 for carrying the line 2 1 to itsdestination. The bodies 46 and 52 and the bearings 50 constitute athrust bearing, so that the hooks 36 are nonrotative notwithstandingrotation of the projectile 42 as it is fired from the barrel l4. Thusthe hooks are prevented from rotating, which might cause damage to thearms 26.

No part of the line 24 lies inside the barrel It, and the projectile isentirely independent of the line 24, or other device to be shot to apredetermined destination or target.

Without further elaboration, the foregoing will so fully explain myinvention, that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.

I claim:

1. The combination of a gun barrel, a projectile to be fired from thebarrel, a carrier, spaced means having resilient devices at their freeends for releasably supporting the carrier at the muzzle end of thebarrel, and hook means pivotally attached to the projectile, and meansfor spreading the hook means apart for connecting engagement with thecarrier as the projectile is fired from the barrel.

2. The combination of a gun barrel, a projectile to be fired from thebarrel, a carrier, arms extending forwardly from the gun barrel, springmeans at the free ends of the arms for releasably supporting the carrierat the muzzle end of the barrel, hook means pivotally attached to theprojectile, spring means for spreading the hook means apart angularlyfor connecting engagement with the carrier as the projectile is firedfrom the barrel, and a bearing interposed between the projectile andsaid hook means to render the hook means nonrotative with respect to theprojectile.

3. The invention described in claim 1 wherein an explosive containingshell is provided, said projectile being attached to said shell, andsaid hook means lying in the explosive.

4. The invention described in claim 1 wherein said projectile has arecess in its rear end, a thrust bearing constrained in said recess, abracket attached to one element of said thrust bearing, a pin attachedto the bracket, said hook means comprising hooks pivotally mounted onsaid pin, and a spring mounted on said pin and engaging said hooks topivot the latter to positions for engagement with said carrier.

FRANK LARVICK.
